Suppose we need a logic circuit with a logic output G that is high only if a certain hexadecimal digit is 1, 5, B, or F. The inputs to the logic circuit are the bits B8, B4, B2, and B1 of the binary equivalent for the hexadecimal digit. (The most significant bit is B8, and the least significant bit is B1.)
a. Fill in the Karnaugh map shown in Figure.
b. Determine the minimized SOP expression for G.
c. Determine the minimum POS expression for G.
